Thanks to a prompt idea from @Mayple ,
we came up with an idea.
(Note: This was on BIONICLE 2015 Discussion Topic, but I think it can go on here too)
(SPECULATION)
It never really states that the Mask of Creation and the Mask of Control were made by Ekimu and Makuta, does it?
They just… had them.
Remember, only the power of the Mask of Creation allows Ekimu to create Masks of Power.
So how could Ekimu make the Mask of Creation if that is the specific mask he needs to make Masks of Power?
Maybe this is where the Mask of Time comes into play somehow?
Maybe…ARTAKHA?!
